Here is an example of how you can program the PU90 ramp and soak controller from your PC by using our free software, hardware needed as below
1)PU90 with RS-485 feature 2)USB to RS-485 adaptor 3)A personal computer(PC)
The curve we are going to cover today has a trajectory as below
Step 1) Curve starts at 100 degree, and takes 60 minutes to heat the system up to 400 degree Step 2) Temperature of the system stays at 400 for 60 minutes Step 3) Temperature drops from 400 to 250 within 120 minutes Step 4) Temperature goes up again from 250 to 300 within 50 minutes Step 5) Temperature stays at 300 for 180 minutes Step 6) Temperature drops from 300 to 100 within 200 minutes Step 7) Temperature stays at 100 for 70 minutes Step 8) Program terminated.
Here is an video tutorial on how you can run the auto-tuning on the this PU90 ramp and soak controller, the auto-tuning process is very important if you want to acheieve an accurate control result, therefore auto-tuning is esstential for a system just been installed on site. this video demostrate on how to engage the auto-tuning, how to choose correct SV for auto-tuning, check the description section of this video for detailed information
Ramp Soak Controllers. This type of controllers changes the setpoint according to the preset program pattern. The program consists of raising/reducing the setpoint (ramp control) and keeping the setpoint at the preset level for a preset period (soak control)
This is a video tutorial on how you can run a specific profile on PU90 ramp and soak profile PID controller 1) There is a simple heating system in the video consists of solid state relay, a light bulb and temperature controller as well as a PT100 temperature sensor. 2)The program executed in the video is a 6 steps program, starts from 0 degree to 30 degree within 5 seconds, step 2 would be hold the temperature at 30 degree for 3 minutes, step 3 bring the temperature from 30 degree to 50 degree within 5 minutes, Step 5, hold the temperature at 50 degree for 3 minutes, Step 6, increase the temperature from 50 degree to 80 degree within 5 minutes and then program stop right there. 3)You can see over the course of the entire program, the temperature and time are changing as per profile pre-programmed. This item is perfect for kiln, oven, furnace, and all kinds of devices that require precise temperature and time control .
Q: What is a ramp and soak controller ?
A "ramp and soak controller" is a device that controls the setpoint of an oven by gradually increasing the setpoint at a predefined rate ("ramping") and then holding it at that value for a specified duration ("soaking"), essentially creating a controlled heating or cooling profile with a gradual transition and a period of constant temperature maintenance; commonly used in applications like ovens and kilns where precise temperature control with controlled heating/cooling cycles is needed.
Key points about ramp and soak controllers:
• Function:
They manage the setpoint of a process by changing it over time according to a pre-programmed pattern, including both ramping up/down and holding at a specific temperature for a set duration.
• Components:
• Ramp: The phase where the setpoint gradually increases or decreases at a controlled rate.
• Soak: The phase where the setpoint is held constant for a defined period.
• Benefits:
• Preventing thermal shock: By gradually changing temperature, it can reduce the risk of damage from rapid temperature fluctuations.
• Even heating/cooling: Ensures consistent processing throughout a material by providing controlled heating and cooling stages.
MTC-P ramp and soak PID profile multile steps controller is a advanced temperature controller, the process value changed based on predetermined ramping rate and soak rate. process value changes based on a curve over time, the output can be Relay to drive an AC contrator, or SSR Drive to drive an external solid state relay, or 4-20mA analog outputs, maximum 4 patterns with each pattern at maximum 8 segments, 4 pattern can be linked together as 1 program with 32 segements. this controller is suitable for application like muffle furnace, high temperature furnace, klin control etc.
MF43H is a touch screen ramp and soak controller, the conventional ramp and soak controllers or some call it profile controllers on the markets are configured via set buttons on the front panel. end user have to go through layers upon layers of parmaeters and navigate through different parameter during the configuration process. the process could be painful and stressed and often times lead to less efficient and frustration. the configuration with our touch screen ramp and soak controller is much more easier, it's easier for end user to pick up the process as they operate the controller like a cell phone. below are some of the basic features with this touch screen ramp and soak profile controller
MF43HYC is a touch screen ramp and soak controller, accessible from PC and cell phone, works with both android and IOS system, built-in datalogging features, and data can be downloaded to PC, this item is perfect control solution for Experimental furnace, ceramic kiln, porcelain oven, Pottery oven, jewelry casting oven etc, the conventional ramp and soak controllers or some call it profile controllers on the markets are configured via set buttons on the front panel. end user have to go through layers upon layers of parmaeters and navigate through different parameter during the configuration process. the process could be painful and stressed and often times lead to less efficient and frustration.
REX C100, C400, C700, C900 is a very popular controller on the markets, comes with relay or SSR Drive output, with 1 alarm and works on wide range of power supply, works with thermocuple and RTD inputs despite the cost being very competetive.
